The new low-profile design of Shimano Shadow RD increases its shift stability and gives the rear derailleur a sleek and integrated appearance. Race endurance is guaranteed, through the optimized slant angle. The wide compatibility of two specific rear derailleurs (SS for cassettes 11-25T to 11-30T and GS 11-28T to 11-34T) will secure a smooth ride in even the highest and steepest mountain areas.

Shimano Ultegra R8050 Di2 Rear Dearailleur is rated 4.0 out of 5 by 4.
Rated 1 out of 5 by OrangeAddict from Great Shifting But Stupidly Fragile I've now had four of these useless items break and they are not repairable. Summary: true cost of ownership of Di2 is £250 a year for a replacement Derailleur

Rated 5 out of 5 by GPops from Absolutely Excellent I bought this to replace the non-functional one (on my son’s bike). The old one had a mechanical issue but had seen a lot of hard use by someone else. This long cage version was to also accommodate a wider ratio rear cassette (coming soon, I’m not buying that one). Replacement was very straightforward and needed very little adjustment to get the jockey wheels in the right place. A wire plugged in and it’s been perfect ever since. I believe that if the old one hadn’t been physically damaged, it would have lasted. I expect the replacement to have typical Shimano top quality and last for a good while.

Rated 5 out of 5 by Velocimo from Improvement on the 6750 Bought to replace crash damaged 6750 derailleur. Nice improvement that keeps the unit closer in and stops small to small cross chaining by default (can be changed if required).

Rated 5 out of 5 by Bobkolo from Shifts great until it doesn’t First one lasted 2,500 km. Bike is meticulously maintained in Southern California. Had 23,000 km on older 6780 version Di2 with nary a missed shift. Hopefully the new R8000 di2 is not a reliability nightmare. This replacement has worked fine for first month.

What's the little black plastic tube in the box?

Just bought this, and there's a small bag inside the box containing a black plastic tube about 15mm long, 3mm diameter. No reference to it in the installation instructions. What's it for?
Asked by: Gordon27
Found the answer, it's a dummy plug for an e-tube port

Cassette compatible

I want to upgrade from di2 32 cassette to the new 34. I believe I will need a new rear mech, but what is the difference between r8000 and r8050. Can I use either one or which is the best? Thanks
Asked by: Pppppppp
You will need the GS mech for this capacity.

Compatibility

Is this rear derailleur compatible with Ultegra R6870 components (cables/battery/junction boxes etc)?
Asked by: mub92
This would be compatible with the 6870 setup

RD SH R8050 DI2 GS-GRY Lever switch

The User Manual for RD SH R8050 DI2 GS-GRY says the Lever Switch that should be switched off before removing the wheel. I cannot locate the switch. The manual says the shape of the lever switch and its position varies with model. Is there a switch on my model and of so where is it? The wheel is hard to remove. I had to take the QR axle out to get the wheel out, which is not usual.
